Grid definition Enter the chainage and the increment of grid points in length and cross direction of the reference line.
Next step
Press OK to proceed to the REFERENCE GRID - SETOUT screen.
REFERENCE GRID -
SETOUT
The signs for the distance and angle differences are correction values (required minus actual). The arrows
indicate the direction to move to get to the setout point.
Next step • Either, press ALL to measure and record.
• Or, press ESC to return to the Enter start chainage of grid! screen and from there, press BACK to
return to the REFERENCE LINE screen.
Field Description
Start Chain Distance from the reference line start point to the beginning grid start point.
Increment Length of incrementation.
Offset Offset distance from the reference line.
Field Description
Chn The chainage of the grid setout point.
Offs Offset increment values. The setout point is to the right of the reference line.
dH.A. Horizontal direction from the measured point to setout point. Positive if the telescope
must be turned clockwise to the setout point.
d.H.D. Horizontal distance from the measured point to setout point. Positive if the setout point
is further away than the measured point.
d.d.z. Height difference from the measured point to the setout point. Positive if the setout point
is higher than the measured point.
Line Grid increment values. The setout point is in the direction from the first to the second
reference point.
dL Longitudinal distance from the measured point to the setout point. Positive if setout point
is further away than the measured point.
dO Perpendicular distance from the measured point to the setout point. Positive if setout
point is to the right of the measured point.
